It might help until somebody knowledgeable posts.
With my limited knowledge of grub (figured out from fiddling with linux distros and messing things up), I think that the instructions in 4.1.2 should get him into Windows.
(In relation to the partition setup, if that is a relatively new Dell, the Windows bootloader might still be on sda1, even though XP is on sda2, because of the way Dell sets up its automatic recovery system. If you try to boot into Windows, I wouldn't assume that you need to boot sda2.)
